Unlock screen freezes on nexusSupport

While playing a game on my nexus, i put the device to sleep. But later when tried to unlock the screen the screen would freeze and when not freezing it would be very slow to unlock. Do not want to delete the game.

Sorry to see you're having troubles with lock screen freeze on your Nexus One.

Often, that can be remedied by going into menu > settings > applications > application manager > (your game causing the issue) and clicking the "clear cache" and the "clear data" buttons, both. Then back out of the menu and reboot the device.
